Hi..
Welcome to HEALTHCARE MAGIC..
I have gone through your query and can understand your concerns..
As per your complain it seems that you are suffering from
throat infection that can be Bacterial throat infection also known as
Strep throat or can also be due to viral infection..
The symptoms of throat pain that is
Pharyngitis along with inflamed tonsils that is Tonsillitis, abscess over tongue and
swollen lymph nodes seems to be due to it..
You can be advised a course of antibiotics that you are already given as
Amoxicillin and will definitely help..
You also need to take anti inflammatory painkillers like Ibuprofen, doing warm saline gargles, steam inhalation and using a humidifier in your room can help..
You can also suck throat lozenges, chew Vitamin C pellet and avoid spicy and chilled foods..
Hope this information helps..
Thanks and regards.
